Japan has established mandatory technical standards for CO2 storage facilities to ensure safety and environmental compliance. This move includes transparency requirements for international trade through WTO notification mechanisms. The standards apply to specific HS codes and are aligned with national technical regulations.

Compliance Overview: Japan’s Mandatory Technical Standards for CO₂ Storage Facilities
Japan has established a regulatory framework for CO₂ storage facilities under the Act on Carbon Dioxide Storage Business (hereafter "the Act"), mandating technical standards to ensure safety and environmental protection. These standards apply to specific products (identified by HS codes) and are enforced through a Ministerial Order issued by the Ministry of Economy, Trade and Industry (METI). The regulations are notified to the World Trade Organization (WTO) under the Technical Barriers to Trade (TBT) Agreement to ensure transparency in international trade.
Regulation Analysis
1. Legal Basis and Scope
The Act on Carbon Dioxide Storage Business forms the foundation for Japan’s CO₂ storage regulations:
- Article 67(1) requires storage business operators to maintain CO₂ storage facilities in compliance with technical standards established by METI1.
- Article 86(1) extends these requirements to CO₂ pipeline transport operators, mandating adherence to technical standards for pipeline facilities1.
- The standards are designed to prevent accidents and protect human health or safety, aligning with existing regulations such as the Mine Safety Act, Gas Business Act, and High-Pressure Gas Safety Act1.
2. Technical Standards and Reference Regulations
The forthcoming Ministerial Order to Provide Technical Standards for CO₂ Storage Facilities will codify the technical requirements. It references three key regulations (available only in Japanese):
- Ministerial Order to Provide Technical Standards for Structures Used in Mining (METI Order No. 97 of 2004).
- Ministerial Order to Provide Technical Standards for Gas Facilities (MITI Ordinance No. 101 of 2000).
- Regulation on Safety of General High-Pressure Gas (MITI Ordinance No. 53 of 1966).
These references suggest the new standards will incorporate provisions for structural integrity, pressure management, and safety protocols from existing frameworks.
3. Product Coverage (HS Codes)
The technical standards apply to the following products, as specified in the WTO notification:
| Product Category | HS Codes |
|---|---|
| Wells | 7304, 7305, 7306 |
| Pumping equipment | 8414.80 |
| Pipelines | 7304, 7305, 7306, 7307 |
4. Compliance Timeline and Process
| Milestone | Date | Authority | Citation |
|---|---|---|---|
| Final date for public comments | 13 October 2025 | Ministry of Foreign Affairs | |
| Proposed adoption date | 21 November 2025 | METI | |
| Proposed entry into force | 22 May 2026 | METI |
- Comment Submission: Stakeholders may submit feedback to the International Trade Division, Economic Affairs Bureau, Ministry of Foreign Affairs by the deadline.
- WTO Notification: The standards were notified under Article 2.9.2 of the TBT Agreement, requiring 60 days for comments.
5. Key Requirements for Operators
The regulations impose the following obligations on operators:
- Facility Maintenance: CO₂ storage and pipeline transport facilities must conform to METI’s technical standards1.
- Safety Protocols: Operators must implement measures to prevent accidents, likely drawing from the High-Pressure Gas Safety Act and Gas Business Act1.
- Documentation and Transparency: While not explicitly detailed in the sources, compliance with technical standards typically requires operators to maintain records of inspections, certifications, and safety assessments.
Summary Answer
Japan’s mandatory technical standards for CO₂ storage facilities are established under the Act on Carbon Dioxide Storage Business, with Article 67(1) and Article 86(1) requiring operators to adhere to METI’s technical standards for storage and pipeline transport facilities1. The standards, to be formalized in a Ministerial Order, reference existing regulations such as the Mine Safety Act and High-Pressure Gas Safety Act to ensure safety and accident prevention1. The regulations apply to products under HS codes 7304, 7305, 7306, 7307, and 8414.80. The proposed adoption date is 21 November 2025, with entry into force on 22 May 2026, following a 60-day public comment period ending 13 October 2025. Operators must maintain facilities in compliance with the standards, though specific technical requirements are not yet publicly available in English.
